SO 14 PSI isn't the minimum setting for the HKS actuator??

Dont know if there are different models but mine certainly goes below 14psi and no doubt will go below 10 if i wanted it to.

Does the turbo run a bored out internal wastegate or is it standard size still?

Standard turbo, unmodified..

Really limited by standard actuator, am looking for an Rb20 unit but they are hard to come by..

Mods (to be installed within the next 3 months).

JJR front dump.

3/3.5 inch custom catback wih 3.5 inch hi-flow cat.

GReddy Spec-M intercooler.

Nismo fuel pump.

Haltech.

All for an R34 GTT.

Following upgrades (mid-2009):

Poncams.

Injectors.

Aftermarket air filtration (either boxed pod or ARC airbox upgrade).

After that I'll be heading for a HKS GTRS..

For the meanwhile though, I want to achieve 12 psi safely. I've heard some not too good things about solely relying on the EBC...

just for reference for the HKS actuator (not sure if this is accurate, do you trust the internet?)

Length is measured from the hat to the end of the rod I think

Length Boost Pressure

128mm .5 bar 7.25psi

123mm .8 bar 11.6psi

121mm 1.0 bar 14.5psi

119mm 1.2 bar 17.4psi

I dont trust that, when i went from .8 to .95 it was about 5mm.

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      R34 25GT Engine Light 21

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
